Most notable among them is “dumpster fire,” a word Merriam-Webster officially defines as “an utterly calamitous or mismanaged situation or occurrence.”

The dictionary even makes a jab at the New York Giants’ abysmal NFL season, citing NJ Advance Media’s James Kratch for how to use the word in a sentence: “Reese and McAdoo take the fall for what has been a dumpster fire of a season, one which has them a 2-10 on the season, and in line for one of the top two picks in the 2018 NFL Draft.”

Another addition to the dictionary commonly used in 2018 is “mansplain,” which Merriam-Webster says has been in rotation among English speakers since 2008. The dictionary defines it as when men “explain something to a woman in a condescending way that assumes she has no knowledge about the topic.” The term “mansplainer” may be used as a noun.

Two other new words that may look familiar, particularly to social media users, are “retweet” and “embiggen,” the latter of which, Business Insider points out, actually has roots in a mid-90s “Simpsons” episode. See below for proof.
